Detailed Product Description

ZZYVP the nitrogen seals the installment (to lead director self-reliant -like pressure regulator valve)

Product outline

The pressure-regulating valve does not need the sur- energy, uses is moved medium own energy is the power supply. The automatic control valve medium current capacity, after causing the valve, pressure maintenance constant pressure stabilization unit. Already widely applied in the natural gas which delivers continuously was mad picks loses, industrial production departments and so on town gas as well as metallurgy, petroleum, chemical industry.
    Valve characteristic: The control precision is high, may compared to general ZZY direct operation pressure-regulating valve high one time about. Adjustment differential pressure compared to before after big (for example valve 0.8MPa, valve 0.001MPa) especially qualify minute pressure gas control.
    The pressure hypothesis realizes on director, thus convenient, quick, reduces effort time-saving to be possible to establish continuously under the running status.
